Document Content and Description Below
1. If all four switches below are turned on, which light bulb will light up? (W is wood, S is silver, and Y is yarn.) A. Circuit A B. Circuit B C. Circuit C D. Ci... rcuit D 2. What will happen when a light bulb is removed from the circuit below, leaving a gap? A. The remaining light bulbs will go out. B. The remaining light bulbs will dim. C. The brightness of the remaining light bulbs will not change. D. The remaining light bulbs will brighten. Correct Answer: A. The remaining light bulbs will go out. Explanation: In the series circuit shown there is only one path for charges to flow. Removing any of the lights will break the circuit, and no charges will flow. 3. What will happen when a light bulb is removed from the circuit below? A. The remaining light bulbs will go out. B. The remaining light bulbs will dim. C. The brightness of the remaining light bulbs will not change. D. The remaining light bulbs will brighten. Correct Answer: C. The brightness of the remaining light bulbs will not change. Explanation: In the parallel circuit shown there are many paths that charges can flow. Removing one of the lights will not change the current in the other lights, so their brightness will not change. 4. What will happen when a light bulb is added on the left side of this circuit (where the arrow is)? A. The remaining light bulbs will go out. B. The remaining light bulbs will dim. C. The brightness of the remaining light bulbs will not change. D. The remaining light bulbs will brighten. Correct Answer: B. The remaining light bulbs will dim. Explanation: In a series circuit like the one shown, adding more light bulbs will decrease the amount of charge that can flow through the circuit. This will cause the light bulbs to dim. 5. What is the role of a fuse? [Show More]
